摘要
A dual carrier modulator that modulates an orthogonal frequency division multiplexing (OFDM) carrier, includes an input part receiving a predetermined number of coded bits; a memory part storing the coded bits received through the input part; a detection part detecting four bits among the coded bits in a predetermined order; and an operation part generating a modulated symbol comprising a real part and an imaginary part, using the four detected bits and a predetermined unitary matrix. Here, one of the detected four bits is included in a real part of a first modulated symbol and in an imaginary part of a second modulated symbol. Accordingly, loss of signals caused by mismatching between an In-phase channel and a Quadrature channel can be prevented.
